Platinum is sold in bars of weights ranging from 17 grams to 1760 grams in 7 gram increments. Each bar is sealed in an opaque box weighing 47 grams . The box used for packaging has no marks on it indicating the weight of the bar inside.
The precious metals merchant selling the boxes has put the packed bars into shelves based on weight. However , to be certain , he weighs the packed box in an equal arms two pan balance, and a set of weights( which is common for all the bars and which he considers as “standard” weights.). Each of these weighs an integral number of grams, and have their weight marked on them. The merchant, a superstitious man, always places the packed box of platinum on the left pan, and places the appropriate weights in the left pan or the right pan or both until balance is achieved. This suffices hi m to tell the weight of the packed bar.
What is the minimum number of “standard” weights the merchant must have to be able to accurately determine the weight of all his packed boxes? how

@ROHIT concentrate on VERBAL part , most of my university studens were not able to clear the verbal cut-off . Do passage at last keep yourself calm so that you can understand questions very well. all d best

An easy way to do these types of questions is considering the question into glasses means consider here that B fills 45 glasses in 45 minutes so A has to feel the same in 37.5 minutes that is it feels 45/37.5 glasses per minute which is equal to 1.2 glasses per minute in 30 minutes tab A will feel 30×1.2 glasses, that is 36 glasses now tap B has to feel only 9 glasses which would take 9 minutes and it's the answer

Number of ways of selecting (3 consonants out of 7) and (2 vowels out of 4)
= 7C_3* 4C_2
= 210.
Number of groups, each having 3 consonants and 2 vowels = 210.
Each group contains 5 letters.
Number of ways of arranging 5 letters among themselves
= 5!
= 120
Required number of ways = (210 x 120) = 25200.
soo ans is(d)
if its wrong means post the correct answer please.

time taken by a in 1 km race= t= 1000 mts/a(speed of a)
in same time b will travel = t=(1000-20)/b(speed of b)
so (98/b) = (100/a)
in 11 km race a will finish race in let p time.
p=11000/a
in that time b will travel distance = p*b=(11000/a)*(98a/100)=10780
hence a beats b by = 11000-10780=220mts

Problem Statement :
# Little Nick loves chocolates and goes to the store with $N money in his pocket. The price of each chocolate is $C. The store offers a discount: for every M wrappers he gives the store, he’ll get one chocolate for free. How many chocolates does Bob get to eat?

only shorthand + know both shorthand and typing=45--------------eq 1
only shorthand+neither know typing nor shorthnad= not know typing=25
only shorthand+10=25
only shorthand=15
in eq1
15+both know shorthand and typing=45
both know shorthand and typing=30
so correct answer is c.
